We measured my daughter and followed the guidelines but this was way too tiny for her. I’d size up. Other than that the quality is great and it’s a really pretty belt.Love this belt it is high quality for sure. We have had it for a few months, and It seems like it will last with our very active 7 year old. We added our own belt buckle to personalize it. The only downside to this is it is not actually beaded just thread to look like beads.
